Installing Javascript machinery

Running the Notebook from the source code on Github requires some Javascript tools to build/minify the CSS and Javascript components. We do these steps when making releases, so there’s no need for these tools when installing released versions of the Notebook.

First, install Node.js. The installers on the Node.js website also include Node’s package manager, npm. Alternatively, install both of these from your package manager. For example, on Ubuntu or Debian:

sudo apt-get install nodejs-legacy npm

You can then build the Javascript and CSS by running:

python css js

This will automatically fetch the remaining dependencies (bower, less) and install them in a subdirectory.
